Preparation and application of sunlight absorbing ultra-black carbon aerogel/graphene oxide membrane for solar steam generation systems.

ABSTRACT: In this study, sunlight absorbing membranes consisting of ultra-black resorcinol-formaldehyde (RF)-based carbon aerogel (CA) and hydrophilic graphene oxide (GO) suspension were fabricated. To investigate the effect of substrate structure, CA/GO ink was cast onto two different layers including 3D modified copper foam (MCF) and 2D paper sheet. The copper foam (CF) was treated with a new and simple modification method to enhance the hydrophilicity. Finally, the solar steam generation performances of the prepared membranes were evaluated. The optical analyses indicated that 2D and 3D samples respectively reflected ∼4.5% and ∼10%, and transmitted ∼0% of the incident light. The water contact angle measurements revealed a significant change in the wettability of the CF layer representing a contac
